Why do people slash and burn their crops?
They didn't slash and burn their crops. They cut down forests(=slash) and set fire to the rest(=burn). This freed up surface area for farming, and the ashes made the ground fertile. Trouble was, they didn't use fertilizers or crop rotation. When they didn't get good yields from their lands they'd simply slash and burn some more. Old farm land was left almost empty of nutrients, with high risk of erosion and poor chances for reforestation.
Does a 1 hour fire resistant door really only last 20 minutes before it burns up in fire?
No. A fire resistance rating is determined by the amount of time a partition will prevent the spread of fire, so a one-hour door (and its wall and supports) would have to hold back a typical fire growing for at least one hour. For example, a 20-minute fire rating requires a fire door to withstand an intense fire on one side, rising to over 1,400 degrees F during twenty minutes, and then being hit by a pressurized fire stream, without causing any openings.
How did people in the Stone age make fire How was fire made in the Stone Age?
I'm not an expert on the mather at hand, but if I'm not mistaken they couldn't make fire yet at the time yet, they "caught"en conderved the fire. after lighting storms hit tree's and started fire's they would then make a holow container of wood and contineu to feed the fire inside the container until they needed it. after that they found out that the fire could burn better in combination with surtain oils and wood types, to the point there on they started simple fire building using rocks to create sparks or wood on wood friction. If you've seen "brat camp", when the kids have to make fire, it's done much like that. "wood on wood friction" ;)
What did the people of the Stone Ages use to clear land for farming with?
During the Stone Age, people used simple tools such as hand axes, adzes, and fire to clear land for farming. These tools allowed them to cut down trees, remove vegetation, and prepare the land for cultivation. Fire was particularly effective in creating open spaces by burning away obstacles like trees and bushes.
Which biome agriculture is commonly practiced in a cut-burn-cultivate-abandon mode?
cut-burn-cultivate-abandon mode?, otherwise known as slash and burn technique. Slash and burn consists of cutting and burning of forests or woodlands to create fields for agriculture or pasture for livestock, or for a variety of other purposes. It is sometimes part of shifting cultivation agriculture, and of transhumance livestock herding. Historically, the practice of slash and burn has been widely practiced throughout most of the world, in grasslands as well as woodlands, and known by many names. In temperate regions, such as Europe and North America, the practice has been mostly abandoned over the past few centuries. Today the term is mainly associated with tropical rain forests. Slash and burn techniques are used by between 200 and 500 million people worldwide. Older English terms for slash and burn include assarting, swidden, and fire-fallow cultivation.Slash and burn is a specific functional element of certain farming practices, often shifting cultivation systems. In some cases such as parts of Madagascar, slash and burn may have no cyclical aspects (e.g., some slash and burn activities can render soils incapable of further yields for generations), or may be practiced on its own as a single cycle farming activity with no follow on cropping cycle. Shifting cultivation normally implies the existence of a cropping cycle component, whereas slash-and-burn actions may or may not be followed by cropping. Therefore, the answer is Tropical Rain Forest.I am a biology professor at John Hopkins.
